Detailed explanation-1: -Computers have two fundamental types of memory-main memory and secondary storage. Main memory is where data and instructions are stored so that they can be accessed directly by the CPU. Secondary storage is used to permanently store data such as the operating system and the user’s files.
Detailed explanation-2: -Comparison Between Primary And Secondary Memories Primary memory is lost during a power outage, while secondary memory saves the data. Primary memory is volatile, while secondary memory is non-volatile. Primary memory is stored on semiconductor chips, while secondary memory is stored on external hardware devices.
Detailed explanation-3: -Difference between Primary storage and secondary storage. Primary memory is the main memory (Hard disk, RAM) where the operating system resides. Secondary memory can be external devices like CD, floppy magnetic discs etc. secondary storage cannot be directly accessed by the CPU and is also external memory storage.
